Aquamarine, Diamanté & Sterling 1940s Earrings

I can’t decide if these sterling silver and diamanté earrings have aquamarine or blue topaz glass stones. Whichever the color, the unusually-shaped stones are faceted and the center of attention.  These unsigned earrings have the same sterling silver clip-backs of another pair by Mazer, so they may be from the same maker. The high quality of these earrings is certainly comparable to Mazer.
